Aston Villa goalkeeper Tom Heaton has called for a review on the offside law after Manchester City's controversial goal on Wednesday night.
Pep Guardiola 's side temporarily moved top of the Premier League table after beating Villa in a hard-fought match at the Etihad Stadium.
The game swung on a controversial moment in the 79th minute when Rodri dispossessed Tyrone Mings, after coming from an offside position, to feed Bernardo Silva, who dribbled through and curled a shot past Emi Martinez.
Smith was sent off for his protests against Silva 's opener and has since been charged by the FA.
The Villa boss revealed why he was sent off by John Moss: "I said to the fourth official David Coote, 'did you get juggling balls for Christmas?' I don't think any other manager would get sent off for that."
The goal has caused a huge debate on social media and across the football community, with the laws of the game showing the goal was correct to stand, although many have argued whether the rule should be altered.
Tyrone Mings has been vocal on social media about a law change and his teammate Heaton has now backed up calls for a review.
“It has (been the talking point for Villa players today)," Heaton told Sky Sports.

"It was a difficult one to take yesterday, albeit looking into it, that is the rule. No, it doesn’t really (make it easier).
"It’s a difficult one to take, when he’s coming from that position, it puts Tyrone in a difficult scenario, there’s an argument to say he should head it away, but for me, there’s an advantage from the offside position.
"I’d probably be looking at that rule if I was the authorities."
